The Hanson Site includes two separate areas of Paleoindian acheological sites in the northern Bighorn Basin of Wyoming, United States.
The southern Hanson I site was investigated first in 1973, finding evidence of tool working and stone flakes at a campsite.
The northern Hanson II site is larger and includes the sites of lodges.
Activity in these areas dates to 10,700 +/- 670 years ago to 10,080 +/- 300 years ago.
The Hanson site is also of interest in paleontology, with animal fossil remains at deeper levels.
